HARRISBURG — Penn State football coach Joe Paterno and other university officials didn't do enough to stop the alleged sexual abuse of children by a former assistant football coach, Pennsylvania's police commissioner said Monday as a scandal at the Big 10 school grows, threatening the legendary Paterno's legacy.

Paterno may have fulfilled a legal responsibility to report suspected abuse by ex-defensive coordinator Jerry Sandusky, "but somebody has to question about what I would consider the moral requirements for a human being that knows of sexual things that are taking place with a child," state police Commissioner Frank Noonan told reporters Monday.

"Whether you're a football coach or a university president or the guy sweeping the building," Noonan said, "I think you have a moral responsibility to call us."

The failure of top university officials to notify police of Sandusky's alleged sexual abuse has outraged students and alumni. Paterno's "success with honor" mantra was the pride of the school that claims ties to one of every 15 Americans with a college degree.

Paterno, who became the winningest coach in Division I football history last week, isn't a target of the investigation by Attorney General Linda Kelly's office. In a statement, Paterno called the charges against Sandusky, 67, "deeply troubling."

"If true, the nature and amount of charges made are very shocking to me and all Penn Staters," he said. "While I did what I was supposed to with the one charge brought to my attention, like anyone else involved I can't help but be deeply saddened these matters are alleged to have occurred."

During a Capitol news conference packed with national and state media, Kelly was asked whether Penn State President Graham Spanier, like Paterno, had been cleared.

"All I can say is again, I'm limited to what's contained in the presentment, and that this is an ongoing investigation," Kelly said.

Noonan said the investigation was about more than football and Penn State. The case is about "children who have had their innocence stolen from them and a culture that did nothing to stop it or preventing it from happening to others," Noonan said.

Sandusky, of State College, is accused of sexually abusing eight boys over 15 years through his charity for at-risk youth known as The Second Mile. He's free on $100,000 bond while he awaits a Wednesday court appearance in Centre County.

Two Penn State officials, athletic director Tim Curley, 57, and Gary Schultz, 62, the university's vice president for business and finance, were arraigned in Harrisburg on Monday on charges that they lied to the grand jury investigating the charges against Sandusky and failed to report the alleged abuse to law enforcement.

While sharp-tongued when it came to the three defendants, Noonan and Kelly offered little new information Monday.

Kelly and Noonan did ask Monday that a child allegedly assaulted by Sandusky in 2002 in sight of a graduate assistant come forward. The graduate assistant told Paterno about the encounter the next morning. Kelly did not rule out the possibility of additional charges.

In all, investigators have identified six of the eight victims included in a grand jury presentment against Sandusky.

"We are determined to quickly respond to any new witnesses or any new information that should appear," Kelly said. That graduate assistant has been identified as Nittany Lions' wide receivers coach and recruiting coordinator Mike McQueary.

"I can say that the graduate assistant reported to Paterno," Kelly said. "Paterno then reported to these school administrators. They were the ones that made the decision to act as they did. And they're therefore responsible, under the circumstances, for the reporting."

In a statement, Paterno said he was "informed in 2002 by an assistant coach that he had witnessed an incident in the shower of our locker room facility. It was obvious that the witness was distraught over what he saw, but he at no time related to me the very specific actions contained in the grand jury report."

"Regardless," Paterno's statement continued," it was clear that the witness saw something inappropriate involving Mr. Sandusky. As coach Sandusky was retired from our coaching staff at that time, I referred the matter to university administrators."

Asked whether anyone at the university had a broader, moral responsibility to share what they knew about Sandusky, Kelly said that, as an investigator, she could only focus on legal guilt.

But Kelly was unsparing in her criticisms of Curley and Schultz, saying, "We cannot condone the actions of those who make false and perjurious statements to a grand jury," Kelly said. "The sexual abuse of a child is a horrific offense that arouses strong emotions within all of us."

Schultz has local ties to the Lehigh Valley. He grew up in the Nazareth area and graduated from Nazareth Area High School in 1967. He graduated from Penn State in 1971 and went to work at his alma mater, rising to the position of senior vice president for finance and business in 1995. In that role, he was in charge of 10 departments, including police and public safety. He held that position until retiring in 2009, but he was brought back on an interim basis in July when the position became vacant.

In September, the university dedicated a new $8.3 million building on the campus in honor of him. It is the Gary Schultz Child Care Center, a day-care facility for children of Penn State students and employees.

At a legal hearing Monday before Magisterial District Judge William C. Wenner, lawyers for Curley and Schultz claimed their clients were the victims of prosecutorial misconduct, snared in what Schultz's attorney, Tom Farrell, called a perjury trap built from inconsistencies in their testimony.

Like Paterno, Curley reported what he knew up the university's chain of command, Farrell said. Both Farrell and Curley's lawyer, Caroline Roberto, added said the law requiring people to report suspected child abuse doesn't apply to their clients because Sandusky's alleged victims were never in the care of the university.

Speaking to reporters later, Roberto called the perjury charge a charge of last resort and the case weak. "They charge it when they can't prove they did anything wrong," Roberto said.

Curley and Schultz arrived separately about 15 minutes before the 2 p.m. hearing to a crowd of dozens of reporters and photographers in the parking lot of a suburban Harrisburg office building that houses the district court.

Inside the small courtroom, Curley, a tall, gray-haired man in rimless glasses, and Schultz, shorter, with close-cropped hair and a mustache, sat at opposite ends of the defendants' table with an attorney between them. Before the hearing and while waiting for court staff to process paperwork, they spoke only with their respective attorneys and not to each other.

During the hearing, called a preliminary arraignment, the men did not enter pleas to the charges. That is likely to occur at a formal arraignment, which has not been scheduled. Wenner allowed Curley and Schultz to remain free on $75,000 unsecured bail, meaning they don't have to put up the money, but will owe the court if they fail to appear for future hearings.

After the hearing, Curley and Schultz pushed their way through a throng of television and newspaper photographers and left together in a black sedan.

In an interview before the administrators' court appearance, Jennifer Storm, of the Dauphin County Victims' Advocate Office and a Penn State alumna, slammed the university's handling of the matter, saying she felt "utter shame," and that her degree from the school had been "tarnished."

"You had at-risk youth who were getting services through an organization that was there to foster their self-esteem, to mentor them," she said. "And you had this big name, Jerry Sandusky, as the person coming in doing this. And for their trust and faith to be violated for the very man who was set in place to protect them is beyond offensive."

Curley and Schultz stepped down from their posts late Sunday, with Curley taking a temporary leave and Schultz retiring.

At the Capitol on Monday, Kelly said inaction by administrators in reporting Sandusky's alleged assaults to law enforcement or a child protective agency "likely allowed a child predator to continue to victimize children for many, many years."

Noonan said he'd never seen a case, in the instance of the conduct reported by the graduate student, where there had been "eyewitness identification of sex acts taking place and the police weren't called."

Noonan said it's not uncommon for sexual predators to pick at-risk children.

"What happened here was grooming, where these predators identify a child, become mentors. Through the charity, Noonan said, Sandusky was "able to identify these children, give them gifts, establish trust, initiate physical contact, which eventually leads to sexual contact. That is very common in these type of investigations."

In a statement released Sunday, The Second Mile group said that Sandusky has had no involvement with The Second Mile programs involving children since 2008, when the former football coach told the foundation that he was being investigated on child-sex allegations.

Noonan and Kelly contrasted the behavior by Penn State to a high school in Clinton County, where Sandusky was barred in 2009 after a student's mother reported allegations of sexual assault. The report to authorities marked the start of the investigation by the attorney general and the state police, they said.

"That really was the catalyst that started this entire investigation," Kelly said.
